Tetra Pak

Tetra Pak, the world s largest producer of food packaging, takes a similar stand "These two principles [precaution and substitution] are important principles in the Swedish national chemical policy and has proven to be a good basis for chemical control. Tetra Pak is therefore supportive to building the REACH system on these two fundamental principles. Precaution and substitution need to be Introduced early in the text as guiding principles for the whole policy""" ...

RTD beverages are also produced in non-carbonated forms. The most popular current form of these is distributed in aseptic card/foil laminate packs, such as Tetra Pak or Combibloc. These drinks are typically unpreserved and come in volumes of 200-330 ml. 

Canned and bottled citrus juices are examples of products that are packed aseptically, and these processes have been used in the industry for many years. One of the newer processes for aseptic packaging employs a paperboard package that is sterilized with hydrogen peroxide prior to the form, fill, and seal operation. This process, developed by Tetra Pak Ab of Lund, Sweden, is in use in many parts of the world, but it has not yet been approved by the U.S. Food and Drug Administration for domestic use. 

The new packaging system developed by Tetra Pak is known as the Tetra Brik , and is generally available in 1-1, 200-ml, and 250-ml sizes. The system is considered to be an alternative to metal and glass containers. The packaging material comes in roll stock form and is a 6-or 7-layer laminate. Polyethylene and aluminum foil offer the major barrier properties to the package. 

Packages of the type used in this study by Garcia are presently used in many parts of the. world for the packaging of milk, juices, and juice products. Brik Pak, Inc., a subsidiary of Tetra Pak Ab has petitioned the Pood and Drug Administration for approval to use the Tetra Brik package in the U.S., but a final decision regarding their petition is still pending. 

A typical 1 L glass bottle for storing milk or juice weighs 400 g, while a 1 L tetra pak carton weighs only 35 g. This implies a big difference in raw material and transportation costs. Glass bottles, however, are often washed, reused, and...

As mentioned in Section 2.2.1, the recovery of clean aluminium from real plastic-containing wastes has been one of the main focuses of the research into microwave pyrolysis. With the semi-batch apparatus shown in Figure 21.3, experiments were performed using toothpaste tube laminate and depulped drink carton laminate (a Tetra Pak ...

Only the EMC extractor (see Eigure 3.9-3.10) and recently, some similar machines from FOMESA (7) and OIC (8) allow a simultaneous collection of rasped peel for oil recovery and juice in separate streams. The juice passes from the extractor to a so-called finisher to remove the coarse pulp particles. Then the juice can be bottled as fresh juice or it can be used for the production of juice concentrate. If necessary, the pulp content of the juice can be further reduced by centrifugation, using so-called desludger type centrifuges (AEEA EAVAE and TETRA PAK (9), WESTEAEIA SEPARATOR (10), etc.). 

In recent years, several new filling systems were developed in order to reduce the heat load necessary for sterilising the juice. For this purpose bottles or soft packages are sterilised before filling. The juice is heated in a closed system and cooled immediately thereafter. The sterilised juice is filled into the sterilised containers at ambient temperature. Glass bottles or cartons and pouches can be used as packaging (Tetra Pak (17), SIG Combibloc (18)).

All diffusion processes involving the transfer of a diffusantfrom or to a polymeric material asymptotically reaches a steady condition at long times. In any closed system (like a Tetra Pak carton) that has reached this condition, there is no effective mass transfer between the polymer and the surrounding phases the adjuvant concentrations are at equilibrium, and the transferred material is at the maximum possible amount In reference to Fig. 11.25 b, consider a sorption or migration process that has reached equilibrium. is the volume of contacting phase, and Vp is the volume of plastic in the container, and c y and c are the equilibrium concentrations of the adjuvant in the contacting phase and polymer, respectively.
